Specicaton of Letters Patent. Patented Dee, 1 9, 1916.

Application'led August 3D, 1916. Serial No. 117,699.

Kinsley, in the county of Edwards, State ofV Kansas, have inventedcertain new and useful Improvements in Push-Poles; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such` as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to devices for connecting tractors with grainheaders, the invention being more specifically a push pole forconnecting such tractors and headers.

vOne important object of the invention is to provide an improved form ofpush pole which may be used to push a header through a field by means ofa tractor, the push pole not interfering in any way with the usualsteering pole of the device.

A second important object of the invention is to provide an improvedgeneral construction of push poles for purposes of this character.

With the above and other objects in view, as will be hereinafterapparent the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and Figure 1 is a side elevation of a pushpole showing the same apy plied to a header and tractor, only parts ofsaid header and tractor being shown. Fig. 2 is a plan view of thedevice. Fig. 3 is an enlarged detail view showing one end of the pushpole in side elevation. Fig. t is a section through such end showing themanner of connecting the various parts by the bolts.

In carrying out the objects of the invention and in the embodimentherein disclosed there has been illustrated the front end of a tractor Aand a portion of a header indicated in general at B. These parts areconnected by a push pole which comprises a plurality of longitudinalmembers 10 preferably of strong but light lumber and between the ends ofsaid members are arranged spacing blocks 11 which hold these ends apart.Intermediate of the ends of the members is also provided athird spacingblock 12 which is of a greater thickness than the spacing blocks 11 sothat the members are bowed outward at the center and thus a strong butlight truss is formed. At each end of the pole there is provided a pairof plates 13, one of each pair of the plates engaging the top of therespective end of the pole while the remaining plate of the'pairvengages the bottom of the pole. Both of the plates in each pair projectover the ends of the members 10 and are provided with vertically alinedopenings 14 therein so that a pivot pin 15 may be removably mounted inthese openings. In order to hold the members, end spacing block andplates together,

bolts lare employed which pass through suitable openings in the plates,the members and the end spacing blocks thus clamping all of these platestogether. Similar bolts 17 hold the center spacing block in position.

Pivoted on each of the pins l5 is a bracket 17 which is provided withone or more bolt receiving openings 18 so that bolts 19 may be used toconnect the bracket to the header or tractor as desired. By means ofthis construction a strong but light push pole is formed which beingpivoted at each end to the respective devices, enables square corners tobe turned in the field by the aid of the guide wheels usually employedon the pole of a header. It will be observed that under these conditionsthe header may turn a sharp corner while the tractor follows around in ashort curve. There has thus been provided a simple and efficient deviceof the kind described and 'for the purpose specified.

It is obvious that many minor changes may be made in the form andconstruction of the invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described but it is wished to includeall such as properly come within the scope claimed.

VI-Iaving thus described the invention, what is claimed as new, is

A push pole for connecting tractors and grain headers comprising aplurality of members extending longitudinally of the pole, spacingblocks between the ends of said members, a spacing block between themembers intermediate their ends, the last- Copies of this'patent may beobtained f or ,to a header.

mounted in the openings of the plates, and brackets pivoted on said pinsand provided with bolt receiving openings whereby to afford means forconnection to a tractor and In testimony whereof, I zux my signature, in.the presence of two witnesses.
